R series of ball bearing for air-conditioning

Q:What is the function of deep groove ball bearings in pairs?: Bearings are used in pairs and symmetrically installed: the internal axial force is balanced so as not to move axially so that the shaft or case can be confined in the axial clearance within two directionsI hope I can help you.

Q:Deep groove ball bearing type: Deep groove ball bearings are the most common types of rolling bearings. A basic deep groove ball bearing consists of an outer ring, an inner race, a set of steel balls, and a set of retaining structures. Deep groove ball bearings are of two types, single row and double row. The deep groove ball structure is divided into two kinds of sealing and open structure. The open type means that the bearings are not sealed. The sealed deep groove ball is divided into dustproof sealing and oil tight sealing.

Q:How can we split the deep groove ball bearings?: The steel cage can be disassembled first.

Q:The deep groove ball bearing rubber ring is too thick. What's wrong with it?: Deep groove ball bearing sealing ring in the case of increased thickness will increase torque, bearing feel bad, service life reduced. Generally non contact, light contact, standard contact! The specific thickness design shall be determined according to the dustproof groove of the ferrule, so as to achieve the desired effect

Q:6010 is the ball bearing deep groove ball bearing?: It is deep groove ball bearing. Its inner diameter is 50mm. It can be imported

Q:What does "6208" in deep groove ball bearing 6208 GB/T 276-1994 mean? Ask God for detailed explanation and dimensional description.: 6 - representing deep groove ball bearings; 2 - representing the bearing width code; 08 - representing the inner diameter of the bearings; 5*8=40mm; specific bearing dimensions; mechanical design manuals

Q:Deep groove ball bearings have an inner diameter of 25 and an outer diameter of 47. How much is the tolerance of the shafts and jackets that match it?: Shafts 24.990 through 25Coats 46.990 to 47

Q:What's the difference between 6000-6012 and 6200-6212 in deep groove ball bearings?: 6 means deep groove ball bearingsThe second bit indicates the width of the series. The model you call here is a narrow series, omitting 0The third digit represents the diameter series code, 0 of which is the special light and the 2 is lightPosition four or five is the inner diameter code, and your number is 12, or 60mm

Q:What's the 6102 specification for deep groove ball bearings?: Internal diameter (mm):15, outside diameter (mm),:32 width (mm),:9 weight (KG):0.026

Q:I want the standard is best GB, and if other mechanical standards are also ok. 2, mainly to bearing diameter tolerance (preferably all grades have).: Deep groove ball bearings are the most commonly used rolling bearings. The utility model has the advantages of simple structure and convenient use. The utility model is mainly used to bear radial load, but when the radial clearance of the bearing is increased, the ball bearing has the performance of a certain angular contact ball bearing, and can bear the combined load of radial and axial. When the speed is higher and the thrust ball bearing is not suitable, it can also be used to bear the pure axial load. Compared with other bearings of the same size, the friction coefficient of this kind of bearing is small and the limit speed is high. But it is not shock resistant and is not suitable for heavy load. The deep groove ball bearings are mounted on the shaft, and in the axial clearance of the bearing, the axial displacement of the axle or the two directions of the outer shell can be limited, so that the utility model can be positioned in an axial direction in both directions. In addition, this kind of bearing also has a certain ability to adjust the heart, when relative to the shell hole tilted 2 'to 10', still can work normally, but it has some influence on the bearing life. The deep groove ball bearing holder is mostly steel plate stamping wave cage, and the large bearing adopts the metal solid cage. Size tolerances and rotation precision tolerances of deep groove ball bearings are widely used in automobiles, tractors, machine tools, motors, pumps, agricultural machinery, textile machinery and other deep groove ball bearing according to GB GB/T307.1-94 divided into P0, P6, P5, P4, P2 five precision grade. They are equivalent to the international standard ISO492, German standard DIN620, Japanese industrial standard JISB1514, and the corresponding accuracy grade of the United States national standard ANSI/AFBMA STD20.
